PLUG CONNEQTER.

Application filed March 23, 1923. Serial No. 627,070.

To all whom it may concern:

Be it known that I, LOUIS E. Islam, a citizen of the United States,residing at Verona, in the county of Essex and State of New Jersey, haveinvented a new and useful Improvement in Plug Connecters;

and I do hereby declare the following, when taken in connection with theaccompanying drawings, and the characters of refer- 1 once markedthereon, to be a full, clear, and

exact description of the same, and which said drawings constitute partof this 'application, and represent in Fig. 1 a plan view, partly brokenaway,

of a plug connegter illustrating my invention.

Fig. 2 a plan view of one of the plug contacts detached, and shown on anenlarged scale.

Fig. 3 a side view of thesame.

This invention relates toimprovement in plug connecters, that is,devices for making electrical connection with flatirons, percolators,toasters, and other articles which are provided with two contact-pinsover which the plug is placed. The object of this invention is toprovide a lug with contactgripping-jaws, which wil readily yield toadmit the contact-pins and make a close and perfect electrical contacttherewith, and the invention consists in the construction as hereinafterdescribed and particularly recited in the claim.

The plug 5 is of any approved form and design, accordin to the purposefor which it is to be use The plug contains two contact-members, eachcomprising what, for convenience, I will term a bottom-plate 6, adaptedto be secured by a screw- 7 in a groove formed for it in the plug 5.This screw also forms a binding-post for one of the circuit wires. Thecentral part 8 of 'this plate is transversely-bowed, and the outer endcurved to form a lip 9. The plate is also formed on opposite sides withperforated ears 10, and near its forward end with downwardly-turned lugs11. The

lip 9 the usual pins enter.

upper member 12 has its central portion 13 bowed, corresponding to theportion 8 of the bottom-plate, and is formed at its outer end with a lip14, between which and the This top-plate is formed with perforated ears15, corresponding to the perforated ears 10, and with lugs 16corresponding to the lugs 11, and also with downwardly-projectingfingers 17, extending into notches 18 in the sides of the lower plate,so that the outer ends of the two plates are kept in align ment. Passingthrough the perforated ears 11 and 15, on each-side, is a bowed spring19, the legs of which have inward bends 21 near their tips, which tipsengage respectively with the lugs 11 and 16, the tendency of thesesprings being to hold the plates. close. together, and the bends 21,bearing upon the edges of the plates, maintain the parallelism, whichmay be further maintained by forming the upper plate with stops 20,which strike the forward ends of the cars 10. As before stated, theplugs are provided with two sets of my improved contacts and applied tothe pins of electrical devices in the usual way for completingelectrical connection therewith. These parts are readily formed andmaintain their desired relative position.

I claim: 80 In an electrical attachment plug the combination with achambered plug-body, of two socket members located therein, eachcomprising two independently-formed, parallel plates shaped to receive aplug axlally between them, and each formed near one end with aperforation and near its opposite end with an ear, and two bowed springsapplied to the edges of the said plates by means of the saidperforations and ears, located in planes at right angles to the planesof the plates, and coupling the same for their substant" lly parallelseparation on the introduct-io of a plug between them. In testimonywhereof I have signed this specification. I
